Blue Spong coral - now white

I got blue sponge coral, about the size of the average hand, this particular one is white (been so sice I got it, actually bought it white). I notice close to where it is attached to the rock ther is a slight change in shade towrad blue but nothing to write home about, maybe the size of a R5 coin. Will this ever recover and completely blue out, or is this actually meant to be white, or is it dead??

me neither and that is what I assumed too - again, just an assumption, I have hunted online for any helpful info but came up empty handed. Even dead - it doesn't seem to be doing any harm but looking like a big piece of white plastic in the tank, adds color for right now and I am not adding anything to the tank for the next few months so unless it poses a threat to the chemical balance which so far it hasn't, it could just "park off and play dead"

I got both of them about 2 weeks ago, looking exactly as they are and hoped they would recover to what they should be. It looks like I may very well be taking them back to whee they came from and get a refund...then bide my time to get something better later on after I have done a little window shopping and research.

the tree sponge is fine, just keep it like Lanzo said, in a darker area, mine looked better after a 2 weeks in the shade spot, if you remove it, please keep it under water putting it in a bag, I learned the hard way

Your orange sponge has nothing to worry about with the lighting you have. I, well the wife with her hard work and my advice that helps a little, has one in our/her nano for about two years in full light. Light will not kill the sponge UV and lack of nutrients will.

About the blue sponge. I put this blue sponge species in the same basket as aiptasia, flat worm, Bryopsis etc. IMO remove it before it takes over your tank.

Never dose anything you can not measure. Especially in a new tank. Iodine is a delicate element. The effect iodine has on sponges is to disinfect/kill bacteria, most non beneficial in other areas. NEVER DOSE IODINE unless you monitor aquarium concentrations.
